This invention relates to containers and particularly to containers of the collapsible tube type. These containers have usually been made of tin, aluminum, lead or metal and the top or discharge end is usually formed integral with the body. The body of the container is generally formed of quite thin material to permit it being compressed and rolled up to discharge the contents, and the necessary rigidity is obtained by making the discharge end or top qui e thick. The outlet is formed in the stiff top and provided with suitable closure means, which may be of the screw cap, automatic or other type.

These metals are comparatively expensive, and further the metal does not lend itself readily to coloring.

My object therefore is to devise a container in which paper or parchment or similar cheap material may be substituted for metal in the body of the container, and I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawing in which Fig. 1 is a plan view of a blank from which the container body is formed;

Fig. 2 a perspective view of the body as rolled;

I Fig. 3 a side view of the body ready for assembly;

Fig. 4 a plan view of the same;

Fig. 5 a vertical section showingthe method of assembling the body and head;

Fig. 6 a side view of the completed container the outlet end being shown in section;

Fig. '7 a sectional view showing a modified form of construction; and

Fig. 8 a side view of the body as shown in Fig. 6 before assembly.

In the drawing like numerals of reference indicate corresponding parts in the diflerent figures. A indicates the body of the container and B the outlet end thereof. The body is formed of paper, parchment or similar material, which may, if desired, be treated with a suitable material to render it moisture proof, as well as proof against damage by the contents of the container. I find, however, that the paper known in the trade as vegetable parchment." is satisfactory for a number of purposes without further treatment.

In the preferred construction, the body is formed from a flat blank of material as shown v in Fig. 1, which is rolled up to the tubular form as shown in Fig. 2. It wil be noted that the blank I is provided with an extension 2 along part of one edge.

This results, when the body-ls rolled up, in the forming of a narrow strip along the upper edge of the body of less thickness than the main part of the container body. Before rolling the material is coated with a waterproof non-cracking glue which, when set, holds the blank in rolled form. I

This upper portion 2 is then bent inwardly as shown in Fig. 3, to form an inwardly directed flange 3, the material being preferably pleated or folded upon itself as shown to avoid slitting of the flange. It will be evident, of course, that instead of rolling up the body from a flat sheet. in the manner described, the body with its integral flange may be moulded or otherwise formed from paper stock.

The head of the tube is formed of a main part provided with an inclined shoulder portion 4 and a central projection 5 through which latter the outlet is formed. This main part is fitted within the end of the body as shown in Figs. 5 and 6. Superimposed on the shoulder portion t is' a clamping ring 5 which frictionally engages the side of the projection 5 either directly as shown in Fig. 5 or through the flange extension 3 as shown in Fig. 6.

In Fig. 7 a modification is shown in which the neck'portion I of the'top has an annular peripheral recess in its under side to receive the flange on the body, and an annular member 8 is forced into the recess to clamp the flange in place.

The head of the tube may be of metal, hard rubber or any other suitable material, although it is preferably formed of an infusible condensation product or a synthetic resin or similar material.

- The lower end of the tube will be flattened out in the usual manner and held closed by means of a clamping strip 9. I

The body may be provided with a paint, enamel, or other finish as desired, and may also have printing or decorating matter applied thereto. If desired, the printing may be applied to the body before rolling takes place.

What I claim as my invention is:-

1. In a container, the combination of a tubular body of paper or paper-like material, having an annular inwardly directed flange at its outlet end; and a top of rigid material for said outlet end, said ,top comprising separate inner and outer members slidably movable relative to one another in a direction longitudinally of the body and between which the said flange is clamped, said members frlctionally engaging one another and normally tending to resist separation, the exterior diameter of the inner member being the same as the interior diameter of the body.

2. In a container, the combination of a tubular body comprising a blank of paper or paperlike material rolled upon itself to form a plurality of plies, and having an annular inwardly directed flange at its outlet end, the side wall portion of said body having a greater number of plies than the flange portion; and a top of rigid material for said outlet end, said top comprising a pair of separate members movable relative to one another and between which the said flange is clamped.

3. In a container, the combination of a tubular body comprising a blank of paper or paper-like material to form a plurality of plies, secured together by a moisture-proof, non-cracking adhesive, and having an annular inwardly directed flange at its outlet end, the side wall portion of said body having a greater number of plies than the flange portion; and a top of rigid material for said outlet end, said top comprising a pair of separate members slidably movable relative to one another in a direction longitudinally relative to one another and between which the said flange is clamped, said members frictionally engaging one another and normally tending to resist separation.

4. In a container, the combination of a tubular body of paper or paper-like material, having an annular inwardly directed flange at its outlet end; and a top of rigid material for said outlet end, said top comprising separate inner and outer members slidably movable relative to one another in a direction longitudinally of the body and between which the said flange is clamped,
